Port Checking:

Unknown: New entry that will be checked as soon as possible (usually less than 15min)

Open: Port was open during last check (time to next check in parenthesis, re-check after 1h)

Closed: Port was closed during last check (time to next check in parenthesis, re-check after 1h) [Your node can be shown as closed but be working fine, the port scanner can be banned by your node for 24h]

Status:

Status

Meaning

Active (100%)

Masternode is listed and has status "1" (masternode list).This is what you want for your masternode.

Inactive (0%)

Masternode is listed but has status "0" (masternode list)Possible reasons:

Masternode is not responding (port 9999 must be open on your firewall, if you see Closed below, there is your problem)

The 1000 DASH were removed from the masternode start wallet

The masternode is getting banned (active on some but inactive on others):Try masternode start with a fresh/new local wallet (don't forget to send your 1000 DASH to that new wallet!!)This will force a new masternode pubkey (I fixed my dmn01 with that trick)

Masternode is not fully active (some, but not all, nodes see it as inactive [with "0" in masternode list] or unlisted [not in masternode list]).The Percentage indicates how many nodes see it as active (the nearer to 100% the better).

Balance:

This is the balance of the pubkey, if more than 1000 DASH then it has a green background (there can be up to 15min delay with true balance).
